* extend "auth policy" vty command with new option "regexp"
* add vty command "authorized-regexp" for setting arbitrary POSIX
regular expression
* add basic vty test
* add optional "regexp" argument to subscriber-create-on-demand vty
command
With those in place we can now set the regexp against which MS's IMSI
will be matched.
If IMSI match the regexp than MS is allowed to access the network. If
subscriber is already marked as authorized in HLR than it'll be allowed
regardless of IMSI matching.
The same way we can decide whether to create subscribers on-demand
basesd on IMSI regexp match. Similar to authorization this restriction
can be overridden by manually creating subscriber via vty, ctrl
interface or directly in HLR.

In case the GMM message did not arrive over a Gb interface, there is no
LLME (and thus the associated pointer is NULL). Don't try to perform
operations on a NULL LLME.

There was a comment in the code that certain GMM messages require a
valid mmctx pointer. However, nothing actually checked if that pointer
was in fact non-NULL. We plainly crashed if a MS would send us the
wrong message in the wrong state.
Original patch by Harald Welte, but it broke message validity checking,
resulting in sgsn_test failure. This re-implements the NULL check in a
different way, as explained by in-code comment.

In c09f8a3b7f as part of a cleanup
I accidently changed the talloc context from "con" to "bsc". The
issue occurred at an earlier commit when assigning req.ctx to the
"wrong" context. The allocation needs to be scoped by the struct
nat_sccp_connection and not the connection from BSC to NAT.
Before we have a nat_sccp_connection we scope the copied imsi to
the bsc_connection and then steal it, but for the identity resp
we will always have a nat_sccp_connection and can already use the
right context.

subscr_name() was called from several places:
* either without a check for subscr being NULL, which for example
was causing a segfault if we hand-over a channel before identifying the
subscriber
* or with an explicit NULL check and the ternary operator (?).
We now simplify the code by checking for the NULL Subscriber in subscr_name()
itself.

In the past, normal migration was possible only if the actual
schema version differed from the version used in DB by 1. For
example, if DB uses an old version 3 and you need to use it
with the code written for version 5, the check_db_revision()
will convert it to 4 and DB will still use incompatible schema
version during Osmo-NITB running time. After next run it will
be converted to version 5.
This patch replaces a set of 'else-if' checks by a 'switch'
without 'break' statements between 'case' labels (waterfall).
It makes you able to migrate from current version to the
latest despite any difference between them.

In commit 4adb136da6 we introduced
a new authentication state SGSN_AUTH_AUTHENTICATE, but we didn't
add that to auth_state_names[] resulting in log messages printing
it abut 'unknown 0x1' rather than something more useful.
The existing GSUP code expected the subscriber data to be piggy-backed
onto the location update response, rather than a separate (and nested)
insert subscriber data request/response phase.
With this patch we should now support both the nested as well as the
piggy-backed version.
In general, if a function generates output data like a msgb (or in this
case filling an osmo_oap_message structure), the output argument
precedes the source. This is what we use all over libosmo*, and it is
modelled after memcpy(), where dst is the first argument, before src.
Let's align osmo_oap_decode(). Intestingly, osmo_oap_encode was already
correct, so the encode/decode functions used different conventions
before.
